Maintaining peak performance in solar energy assets requires more than occasional visual inspections. Hidden faults, hotspots, or under-performing modules can significantly reduce energy yield over time — unless they’re detected early.

Enter thermography inspections — an advanced diagnostic tool that reveals problems invisible to the naked eye. At HST Nordic, we offer high-precision thermal inspections using both drone and handheld thermal cameras to ensure your solar plant runs at maximum efficiency.

What Is Thermography?

Thermography uses infrared imaging to detect heat variations across solar modules, inverters, and electrical components. These heat signatures highlight:

• Defective cells or strings

• Hotspots indicating electrical issues

• Loose or damaged connections

• Underperforming sections of the plant

This insight helps asset owners catch issues early — before they turn into costly failures.

Drone-Based vs. Manual Inspections

HST Nordic provides two main thermography services:

• Drone surveys for fast, full-plant thermal imaging — ideal for large arrays.

• Manual camera inspections for detailed, targeted checks on specific problem areas.

Both methods are backed by advanced analytics from our exclusive partner Sitemark, ensuring actionable results you can trust.

Why Thermography Matters

Regular thermal inspections help you:

• Maximize energy production

• Reduce unexpected downtime

• Extend the life of your assets

• Make informed maintenance decisions

Solar plants are long-term investments — and thermography is a cost-effective way to protect that investment.
